1. Revise 11.1.5 to read as follows:

11.1.5 Organizations, ISPs, or manufacturers verified to the 2014 edition of NFPA 1851 shall undergo verification to the 2020 edition of NFPA 1851 within 12 months of the NFPA effective date for the 2020 edition, with the exception of the requirements for demonstrating cleaning and sanitization effectiveness specified in 11.3.7.

2. Insert new paragraphs 11.3.6.1, 11.3.6.2, and A.11.3.6.2 to read as follows:

11.3.6.2* For the purpose of verification of advanced cleaning and sanitization, the certification organization shall review the respective facility to determine the equipment and procedures that, through engineering judgment, will result in the lowest level of cleaning. The equipment and procedures shall be selected and subjected to the verification procedures in 11.3.7.

A.11.3.6.2 The engineering analysis should consider the type of detergent used, the wash and rinse temperatures, water levels applied, and time for each specific step of the wash or sanitization formulation and procedures. For example, if a presoak is only used for some formulations in cleaning or sanitizing garment outer shells, then it should not be used as part of the verification of the advanced cleaning or sanitization procedures.

11. Replace Figure 12.9.3.1 with the following:

Insert new figure:

Figure 12.9.3.1 Steps for Folding and Placing Panel A into Wash Load.

12. Replace current Figure 12.9.3.5 with the following:

Figure 12.9.3.5 Steps for Folding and Placing Panel E into Wash Load.

13. Replace current Figure 12.9.3.7(a) with the following:

Figure 12.9.3.7(a) Sequence for Placing Panels in Washer/Extractor Drum.

14. Replace current Figure 12.9.3.7(e) with the following:

Figure 12.9.3.7(e) Placement of Panel D into Washer/Extractor Drum.

15. Add new 19.9.3.7.1 to read as follows:

12.9.3.7.1 It shall be permitted to place the wash load with all of the panels at a 90-degree angle with respect to their orientations shown in 12.9.3.7.

16. Revise 12.9.3.8 and A.12.9.3.8 to read as follows:

12.9.3.8* The sequencing of panels shall be as follows:

(1) The sequencing shall be repeated for attaining a wash load with the mass capacity, ± 5 percent, as specified by the cleaning facility.

(2) Panel D and Panel E shall be alternated in the sequencing.

(3) A total of three panels each shall be used for Panel D and Panel E.

(4) Panel D and Panel E shall alternatively be evenly distributed within the wash load so that there are a near equal number of nonsurrogate panels between each surrogate garments (Panel D or Panel E).

(5) It shall be permissible to adjust the sequence of the panels to meet the requirements of 12.9.3.8(1) through 12.9.3.8(4) in order to attain the target wash load mass capacity.

A.12.9.3.8 Specific examples of samples (panels) are given below for set size washer/extractors in Table A.12.9.3.8(a) through Table A.12.9.3.8(c). These tables are intended to provide examples for how Panel D and Panel E are alternated and distributed with the respective wash loads. The specific panel weight can vary based on cutting practices and use over time.

The Examples of recommended sequencing sequences for individual panels for a 40 lb, a 60 lb, and a 100 lb washer/extractor load at 80 percent capacity are provided in Table A.12.9.3.8(d).

Substantiation: The revision in paragraph 11.1.5 is to remove ambiguity for the grace period that was modified by NITMAM NFPA 1851-1.

New paragraphs 11.3.6.1, 11.3.6.2, and A.11.3.6.2 clarify how certification organizations apply cleaning and sanitization verification procedures to ISPs with multiple locations and processes.

Revisions to 12.4.3.2 and 12.5.3.2 provide needed detail for the preconditioning of fabric samples to be used as cleaning and sanitization verification specimens.

New paragraphs 12.4.4.5.3.1 and 12.5.4.5.4.1 permit faster drying of specimens, which assists certification organizations in maintaining greater control and precision in evaluation the effectiveness of cleaning and sanitization verification.

The revision to paragraph 12.7.2.4.4 corrects an error in the specified time for drying specimens contaminated with heavy metals.

Revisions to sections 12.9.1.4 and 12.9.1.5 ensure that the specific surrogate garments match those garments that were used to validate the procedures for cleaning and sanitization verification that were adopted as part of the standard.

Revisions to Figure 12.9.2.7, 12.9.3.1, 12.9.3.5, and 12.9.3.7(a) ensure that the wash load procedures match those surrogate garment and wash load procedures that were used to validate the procedures for cleaning and sanitization verification that were adopted as part of the standard.

The addition of paragraph 12.9.3.7.1 allows the better positioning of the load to accommodate washer/extractors with smaller drums used in verification of advanced cleaning and sanitization.

Revisions to 12.9.3.8 and A.12.9.3.8 remove contradictory language between the annex and the mandatory language in the standard for creating the wash load.

Emergency Nature: The standard contains an error or an omission that was overlooked during the regular revision process. The NFPA Standard contains a conflict within the NFPA Standards or within another NFPA Standard. The proposed TIA intends to offer to the public a benefit that would lessen a recognized (known) hazard or ameliorate a continuing dangerous condition or situation.

The proposed changes also remove contradictions between figures and stated language, and with the original validation work undertaken by the Fire Protection Research Foundation. These changes further provide clarifications that enable certification organizations to carry out procedures for verification of advanced cleaning and sanitization that are currently inhibited by existing requirements in the standard.
